基于ArcGIS的1∶10000地形图符号化模板制作研究

Study on the Production of 1∶10000 Scale Topographic Map Symbolization Template Based on ArcGIS

地图符号是对地理空间事物的抽象表达,符号库即是符号的有序集合。ArcMap中自带的符号库不能满足国家基本比例尺地图输出的要求,本文结合AutoCAD和FontCreator等软件,基于ArcGIS设计制作符合国家标准图式要求的数据库符号化模板,从而实现了对gdb/mdb格式1∶10000比例尺地形图的符号化显示。并且利用Python语言编写ArcMap下的数据处理插件,完成gdb/mdb数据自动合并,大大地提高了工作效率。通过对模板图层的实际使用,验证了其高效性、便捷性和稳定性。

The map symbol is the abstract expression of geospatial objects.The symbolic library is an ordered set of symbols.Symbolic library in Arc Map cannot meet the requirements of the national fundamental scale map output. Comparing with Auto CAD and Font Creator,this paper produces the database symbolic template of national fundamental scale topographic maps based on ArcGIS. Thus,the symbolic display of 1 ∶10 000 scale topographic map in gdb/mdb format is realized. The data processing plug-in developed by Python under Arc MAP can merge data in gdb/mdb format,and it can improve the working efficiency greatly. The efficiency,convenience and stability of the template has been verified in practical map output.
